ELTJAH LA K'E, OF DA VISBURG, MICHIGAN. Letters Patent No. 68,996, dated iSYeptentlw-r 17, 1867.

, tmovtnm 11v GRAIN-DRILLSt TO ALL WHOM IT MAY CONCERN:

3e it known that I, ELIJAII LAKE, ofDavishui-g, in the County of Oakland, and inth e State of Michigan,

have invented certain new and useful Improvements in Grain-Drills; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon In the annexed drawings, making part of this specification A represents the frame of tlie nachine, which simply consists of two side rails placed at asuitable distance apart, and connected by two cross-pieces, one at rear and the other in front. This frame rests upon a crossshaft, l), which said shaft is supported upon a series of rollers, C C 0, there being a rollerfor 'eachdrill-tooth.

Near one end of shaft B, and outside of theframe, is a gear-wheel, D. This gear-wheel is placed upon shaft B 3 loose, but is made permanent 'upon the shaft by means of the collar B. This collar R slides upon the endof shaft B, and is provided with a pin, S, which catches against a pin, t, on the outer face of the wheel D when it i is necessary to make said wheel permanent upon shaft 13. This collar is not allowed to revolve independently of the shaft, and it is slid to or from the wheel D by means of a lever, g, which connects with it, havinga pronged end whichembraces the collar, working in a groove near its outer end. J and Krepresent two seed boxes, one for grass and the other for grain. Through these seed-hoppers or boxes passtwo shafts, I and E. On theouter end of shaft I is a gear-wheel, H, and on the outer end of shaft E is a gear-wheel, G. Thesetwo 3 wheels mesh together. F" represents an idle-wheel, which is situated between wheel I) and wheel G, andcom-t municates motion from wheel I) to wheel G. M M represent the ordinary drag-bars, which are hingedat the 1 forward part of the machine to a rod, '1. The drill-teeth L are connected to the rear ends of these bars. N N represent chains, which connect the drill-teeth to the crossbar O. The cross-bar O is provided with a. lever t handle, it, which serves to raise and lower it. This lever-handle is stationed by catching it in one of a series 1 of notches cut in the edge of a standard, W. By means of this handle it the drill-teeth are elevated or lowered i at the will of the operator. V represents the drivers seat, which is placed upon thc rear end of the frame .A.

This machine operates as follows: Seed being placed in the hoppers, and the machine beingdrawn forward, the rollers C C, which rest upoh the ground, revolve "and give motion to the wheel D, and this wheelfl through the idleqvlicel, communicates motion to the shaft of the seed-hoppers, through their wheels Hand The revolving of the shafts E and I agitates thcsecd and causes it to pass through the. openings in the bottom of the hoppers, which are constructed in any of the knownand usual ways. The rolleisC G roll over the ground in rear of the seed-discharge spouts and pack the drills. It will be seen that the drill-teeth L are provided with i wings 1? upon theirbacks, and these rings cover the grain as fast as it is dropped from the teeth. The rollersl 1 pack the earth as fast as it is turned over the grain by the wings P. By means of the le'verq the collar R can;

hemoved from contact with the wheel D; this stops the motion of said wheel, and consequently the motion of f the shafts E and I, and the stoppage of these shafts necessarily causes the flow of seed from the hoppers'to cease. Having thus fully described my invention, what I claim 'as new, and desire to secure by Letters Patent, is- 1. Providing the drill-teeth L with wings P, substantially as and for the purpose set forth; 2. The use of a series of rollers, G G, in combination with the winged drill-teeth for, packing-the earth after the wings, substantially as set forth. r 3. The arrangement of the collar R upon the shaft B, with the wheel D and lover 9, whereby the seed. shafts are thrown in and out of gear, as and for the purpose set forth. In testimony that I claim the foregoing invention I have hereunto set my hand this 31st day of May, 1867-. f
